TELEPHONE SET, COMMUNICATION SYSTEM,
AND METHOD OF SETTING SECURITY FUNCTIONS IN TELEPHONE SET
FIELD OF THE INVENTION
The present invention relates to a telephone set such as a
portable telephone set or the like having security functions
for-preventing a third party from unauthorized use thereof, a
communication system with the security functions provided in a
side of a network, and to a method of setting the security
functions therein.
BAOKGROUND OF THE INVENTION
Provided in this type of telephone set is, generally, a
security function (described as a locking function
hereinafter) with which the telephone set is disabled to be
used unless a correct identification number is inputted
thereinto to prevent any person other than an authorized owner
of the telephone set from using it without authorization.
Namely, the locking function is unlocked in response to input
of the correct identification number thereinto.
As a conventional technology relating to this type of
locking function, there is Japanese Patent Laid-Open
Publication No. SHO 61- 236226. In this Publication, there is
disclosed a technology that calls are transmitted from a mobile
telephone set or received thereby by inputting an
- 1 -
CA 02214197 2000-02-23
28964-9
identification number thereto at the time of using the mobile
telephone set and obtaining identification by collating it to
the identificatio:z number previously stored therein.
There has been proposed a telephone set in which a
security function is provided so that a particular number such
as a telephone number for a long-distance call or the like
(described as a cell-restricting function hereinafter) is
restricted. In this case, the call-restricting function is
also unlocked in response to input of a correct identification
number thereinto.
In the conventional type of telephone set as
disclosed in the publication, unlocking of a locking function
and a call-restricting :function is first set according to input
of an identificatuon number and call setting is carried out,
which makes the operations complicated.
After tree cal:L is unlocked, and when prevention of
unauthorized use of a telephone set or a restriction of
particular number: are also required for the next use thereof,
the locking function and the call-restricting function are
necessary to be set aga_Ln, which makes the setting of a
security function there_Ln troublesome.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Detailed description is made hereinafter for preferred
embodiments of the telephone set, communication system, and
method of setting security functions in a telephone set
according to the present invention with reference to the related
drawings.
The description made hereinafter assumes a case of a
portable telephone set such as a PHS (Personal Handy Phone
System) in which call setting is executed through a radio
communication with a base station. Fig. 1 is a block diagram
showing internal configuration of a telephone set according to
Embodiment 1 of the present invention. The telephone set shown
in Fig. 1 comprises units such as a control section 1, an ID
(identification number) storage section 2, a voice processing
section 3, a radio section 4, an antenna 5, a key-entry section
6, a display section 7, a microphone 8, and a speaker 9 each
connected to an internal bus 10 for transferring addresses,
data, and control signals or the like therethrough.
The control section 1 comprises, although it is not shown
herein, a CPU operating according to a control program, a ROM
for storing therein the control program, and a RAM used as a
work area for the CPU, and controls each of the units connected
- 9 -
CA 02214197 1997-08-28
to the internal bus 10 in accordance with the control program
stored in the ROM_ It should be noted that a control program
according to the flow chart shown in Fig. 3 is included in a
call-setting program stored in the ROM. The contents of the
control by this control section 1 cover an operation of verifying
an identification number based on an identification number to
be stored in the ID storage section 2, an operation of voice
processing in the voice processing section 3, an operation of
data transaction in the radio section 4, an operation of key
entry through the key entry section 6, an operation of display
in the display section 7, an operation of voice input through
the microphone 8, and an operation of voice output through the
speaker 9 or the like.
The ID storage section 2 is a memory, to prevent a third
party from executing unauthorized use of a telephone set, for
previously storing therein identification numbers each collated
to an inputted identification number. The voice processing
section 3 is an audio CODEC for modulating an speech signal
inputted therein through the microphone 8 to output the signal
to the radio section 4 and demodulating an speech signal
(modulated signal) inputted from the radio section 4, when it
is a voice communication, to output a voice to the speaker 9.
The radio section 4 is a radio unit connected to the antenna
5 for radio signal transaction through the antenna 5. The
antenna 5 captures radio waves (radio signals) sent from a base
- 10 -
CA 02214197 1997-08-28
station not shown herein, and sends out electric waves (radio
signals) to the base station.
The key entry section 6 has keys such as numeric keys, a
"~k" key 6a, a "SEND" key 6b, and function keys or the like, and
supplies a key-entry signal detected according to an input
operation through each key to the control section 1. It should
be noted that the "~k" key 6a is used for inputting
discrimination code for an identification number and the "SEND"
key 6b is used for instructing call setting at the time of
setting a call.
The display section 7 is a display unit such as an LCD or
an EL or the like, and displays input information through the
key entry section 6, data received from the base station which
is not shown herein, and a state how the telephone set is
working. The microphone 8 is an input unit for supplying input
voice to the voice processing section 3 as an speech signal,
and the speaker 9 is an output unit for voice-outputting an
speech signal received from the voice processing section 3.
Next description is made for call-setting information. Fig.
2 is a view showing an example of a format for call-setting
information according to Embodiment 1, and the reference code
DT indicates call-setting information, TEL indicates a
telephone number, DC indicates discrimination code for
discriminating a telephone number from an identification
number, and ID indicates an identification number respectively.
- 11 -
CA 02214197 1997-08-28
The call-setting information DT is input information for
setting a call with a party ofcall connection (a called party
or a party of data communications) and has a format comprising
a telephone number TEL, discrimination code DC, and an
identification number ID. It should be noted that the
discrimination code DC indicates data inputted through
operation of the "~k" key 6a in the key entry section 6.
Next description is made for operations. Fi-g. 3 is a flow
chart for explanation of call-setting operations according to
Embodiment 1. In the operations, it is assumed that the power
sour-ce has already been turned ON so that a call or a data
communication is ready to be executed.
When a call is to be set, at first, call-setting information
is inputted through key operations in the key entry section 6
in the order of a telephone number TEL, discrimination code DC,
and an identification number ID (step S1). The control section
1 confirms an end of inputting the call-setting information
according to the operation of the "SEND" key 6b in the key
entry section 6.
When a telephone number TEL of "123-456-7890" and an
identification number ID of "1111" are to be inputted, at
first, input of numbers in the order of 1, 2, 3 ~~~ 9, 0 with
the ten key, input of discrimination code with the "~k" key 6a,
and further input of numbers in the order of 1, 1, 1, 1 with the
numeric keys may successively be executed. Then, when the
- 12 -
CA 02214197 1997-08-28
"SEND" key 6b is operated, data "1234567890 * 1111" which has
been inputted before the "SEND" key is operated is stored in
the RAM of the control section 1 as call-setting information
DT. Description is made hereinafter for the operations
according to this example.
Before call setting is executed, the discrimination code
DC (~k) is detected from the call-setting information DT
inputted in step S1. Namely, input of the identification
number ID is checked. When the discrimination code DC (*) is
detected in this detecting operation, it is determined
according to the detected discrimination code DC (~k) that, in
the inputted call-setting information DT, the data inputted
before the discrimination code DC (*) is a telephone number TEL
and the data inputted after the discrimination code DC (*) is
an identification number ID. With this determination, the
call-setting information DT is separated into the telephone
number TEL (1234567890) and the identification number ID
(1111) , and each of the numbers is stored in the RAM of the
control section 1 as one unit of discrete data respectively.
When the discrimination code DC is not detected from the
inputted call-setting information DT, it is determined that an
identification number ID does not exist in the call-setting
information DT, which makes it impossible to discriminate the
telephone number from the identification number (step S2).
Accordingly, when an identification number ID is present
- 13 -
CA 02214197 1997-08-28
therein (step S3), the identification number ID previously
stored in the ID storage section 2 and the identification
number ID discriminated in step S2 are collated with each other
(step S4). As a result, if the identification number in the ID
storage section 2 is "1111", both of the numbers are identical
to each other (step S5), and in this case, the functional
restriction for call setting previously set in the telephone
set is unlocked (step S6). It should be noted that the
functional restriction for this call setting includes a locking
function for call setting to prevent a third party from
executing unauthorized use of a telephone set and a restricting
function of particular numbers (a telephone number with which
a long-distance call will be made or the like). With either of
the functions, effects as security functions can be achieved.
As described above, when the functional restriction for call
setting is unlocked, the telephone number TEL discriminated in
step S2 is read out from the RAM, and the call setting is
executed according to the telephone number TEL (step S7).
When discrimination can not be executed in step S2 and
existence of an identification number in data is not recognized
in step S3, or when the identification number in the ID storage
section 2 is "2222" which indicates that both identification
numbers are not identical to each other, it is determined that
the current request for call setting does not satisfy the
necessary conditions. As a result, the call setting requested
- 14 -
CA 02214197 1997-08-28
by the user is refused (e.g. the locking function) or
restricted (e. g. the function of restricting a particular
number) according to the functional restriction for call
setting preset in the telephone set (step S8).
It should be noted that, for the functional restriction for
call setting, a flag, for instance, may be provided in the
control section 1 so that the CPU can determine the data by
correlating an ON/OFF state of the flag with a setting/
unlocking state of the restriction thereof respectively.
Accordingly, when a functional restriction in call setting is
set, the flag is set to be ON and when the restriction is
unlocked, the flag is reset to be OFF.
As described above, with Embodiment 1, call-setting
information DT including a telephone number TEL and an
identification number ID is inputted into a telephone set at
the time of setting a call, the identification number ID is
determined from the call-setting information DT and collated
with the previously stored identification number, and only when
it is determined that both the identification numbers are
identical to each other, the specified call restriction is
unlocked and call setting is executed, so that input at the
time of setting a call can be executed with one operation,
which makes it possible to simplify the operations for call
setting following the security functions.
Also, a telephone number TEL and an identification number
- 15 -
CA 02214197 1997-08-28
ID inputted with one operation can be discriminated from each
other with discrimination code DC, so that a telephone number
TEL as well as an identification number ID can continuously be
inputted if the discrimination code DC is inputted therebetween
at the time of inputting call-setting information DT into a
telephone set.
In the embodiment 1, an identification number is verified
at the side of a telephone set, but like in Embodiment 2 as
described below, an identification number may be verified at
the side of a network. It should be noted that, in Embodiment
2, a telephone set is also configured by the blocks (Refer to
Fig. 1), like in Embodiment l, including the key-entry section
6 through which call-setting information DT (Refer to Fig. 2)
can be obtained by successively inputting a telephone number
TEL, discrimination code DC, and an identification number ID
to the telephone set.
At first, description is made for a communication system
according to Embodiment 2. Fig. 4 is a view showing one
example of communication system according to Embodiment 2 of
the present invention. The communication system shown in Fig.
4 comprises a base station 100 positioned at the side of a
network NET as well as a telephone set (only one unit of
telephone set 200 is shown herein as an example) connected to
each other through radio communications. Provided in the base
station 100 is an identification-number DB (database) 101, and
- 16 -
CA 02214197 1997-08-28
in this communication system, a verifying function of
identification numbers is added to the base station 100.
Next detailed description is made for the base station 100.
Fig. 5 is a block diagram showing internal configuration of the
base station 100 according to Embodiment 2. The base station
100 shown in Fig. 5 comprises units such as the identification-
number DB 101, a control unit 102, a radio unit 103, an antenna
104 each connected to a bus 105.
The identification-number DB 101 previously stores therein
telephone numbers correlated with identification numbers
respectively each subscribing to the communication system. As
an example, a telephone number of "012-345-6789" is stored
therein correlated with an identification number of "2222", so
that it is a must that the identification number of "2222" is
included in the call-setting information by the originating
user to execute the call setting. Similarly, a telephone
number of "345-678-9012" is stored therein correlated with an
identification number of "3333", so that it is also a must that
the identification number of "3333" is included in the call-
setting information by the originating user to execute the call
setting.
The control unit 102 incorporates therein a microcomputer
and controls radio communications with each telephone set
within an area of which the base station 100 is in charge. This
control unit 102 stores therein, for instance, a program for call
- 17 -
CA 02214197 1997-08-28
setting following the flow chart shown in Fig. 6, and the call
setting is performed according to this call-setting program.
The radio unit 103 is a unit connected to the antenna 104
for radio-signal transaction through the antenna 104. The
antenna 104 captures radio waves (radio signals) sent from each
telephone set (e.g. from the telephone set 200) and sends out
radio waves (radio signals) to each of the telephone sets (e. g.
to the telephone set 200).
Next description is made for operations. Fig. 6 is a flow
chart for explanation of the operations of call setting
according to Embodiment 2. When a call is to be set, like in
Embodiment l, in the telephone set 200, at first, call-setting
information is inputted through key operations in the key entry
section 6 in _the order of a telephone number TEL,
discrimination code DC, and an identification number ID. The
control section 1 confirms an end of inputting the call-setting
information DT according to the operation of the "SEND" key 6b
in the key entry section 6. .
Then, the call-setting information DT inputted in the side
of the telephone set 200 is transmitted from the telephone set
200 to the base station 100. The telephone set 200 ends all the
processing for call setting allocated to the terminal side by
operating this transmission. Namely, in Embodiment 2, the
identifying operation of identification numbers before call
setting is executed is allocated to the base station 100.
- 18 -
CA 02214197 1997-08-28
In the base station 100, a request for call setting is
received according to reception of the call-setting information
DT from the telephone set 100 (step S21). Then, before the call
setting is executed, discrimination code DC is detected from
the call-setting information DT received in step 521. When the
discrimination code DC is detected in this detecting operation,
it is determined according to the detected discrimination code
DC that, in the inputted call-setting information DT, the data
arranged before the discrimination code DC is a telephone
number TEL and the data arranged after the discrimination code
DC is an identification number ID. With this determination,
the inputted call-setting information DT is separated into the
telephone number TEL and the identification number ID, and each
of the numbers is stored in the RAM of the control unit 102 as
one unit of discrete data respectively.
When the discrimination code DC is not detected from the
received call-setting information DT, it is determined that an
identification number ID does not exist in the call-setting
information DT, which makes it impossible to discriminate the
telephone number from the identification number (step S22).
Accordingly, when an identification number ID is present
therein (step S23), the identification number previously stored
in the identification-number DB 101 and the identification
number ID discriminated in step S22 are verified against each
other (step S24). Herein, the identification number used for
- 19 -
CA 02214197 1997-08-28
verification in the identification-number DB 101 is the
identification number correlated with the telephone number TEL
discriminated in step S22 stored therein because telephone
numbers TEL are correlated with identification numbers ID one
by one.
As a result of the verification therebetween, when it is
determined that the identification numbers are identified to
each other (step S25), the functional restriction for call
setting (the locking function and function of restricting
particu7~ar numbers each described in Embodiment 1) preset in
the side of the base station 100 is unlocked (step S26).
As described above, when the functional restriction for call
setting is unlocked, the telephone number TEL discriminated in
step S22 is read out from the RAM, and the call setting is
executed according to the telephone number TEL (step S27).
When discrimination can not be executed in step S22 and
existence of an identification number in data is not recognized
in step 523, or when the identification numbers are not
identified to each other, it is determined that the current
request for call setting from the telephone set 200 does not
satisfy the necessary conditions. As a result, the call
setting requested by the originating user (the telephone set
200) is refused (e. g. the locking function) or restricted (e. g.
the function of restricting a particular number) according to
the functional restriction for call setting preset in the base
- 20 -
CA 02214197 1997-08-28
station 100 (step S28).
As described above, with Embodiment 2, the side of the
telephone set 200 inputs call-setting information including a
telephone number and an identification number at the time of
setting a call to transmit the data to the base station, and the
base station 100 receives the call-setting information,
discriminates an identification number from the call-setting
information to be verified against the previously stored
identification number, and only when it is determined that both
the identification numbers are identified to each other, the
specified call restriction is unlocked to execute the call
setting, so that an inputting operation at the time of setting
a call in the side of the telephone set 200 can be executed
with one operation, which makes it possible to simplify
operations for call setting following the security functions
on the system.
In Embodiment l, the call setting is restricted or refused
when an identification number is not present in call-setting
information, however, like in Embodiment 3 described below, re-
entry of an identification number may be requested to the user
just in case it is failed to be inputted or some other reason.
A telephone set according to Embodiment 3 is configured by
the blocks shown in Fig. 1 like that in Embodiment 1, so that
the same reference numerals are assigned to the units
corresponding to those in Fig. l, and description on the
- 21 -
CA 02214197 1997-08-28
configuration and the functions is omitted herein.
Next description is made for operations. In this description
on the operations, the same step numbers are assigned to each
of the processing corresponding to those in Embodiment 1, so
that description thereof is omitted herein, and description is
made herein only for different processing therefrom.
Fig. 7 is a flow chart for explanation of operations for
call setting according to Embodiment 3 of the present
invention. In Embodiment 3, like in Embodiment 1, the
operations from step Sl to step S8 are executed, however, when
existence of an identification number can not be recognized in
data, re-entry of an identification number is requested to the
user.
Namely, when existence of an identification number ID
therein could not be recognized in data in step S3, the
processing shifts to step S9 and requests input of the
identification number to the user before the operation is
shifted to execution of the call setting. There are used
methods, for this request, of displaying the request indicating
re-entry of the identification number by the useron the display
section 7 as a message thereto, of outputting it through the
speaker 9 as an aural guidance, or of outputting it through the
speaker 9 as a notice sound.
After this operation, when the key operation by the user is
detected, the received characters are accepted as an
- 22 -
CA 02214197 1997-08-28
identification number (step S10). However, when the telephone
set is made to execute other function with the function keys,
other processing corresponding to the function keys is executed
by departing from the flow chart shown in Fig. 7.
When reception of the identification number could be
recognized in step 511, the processing shifts to step S4, and
the identification numbers are verified against each other as
described above. After this operation and on, the same
processing as that in Embodiment 1 is executed. It should be
noted that the code "~k" has to be provided in front of a numeric
array of the identification number to recognize an
identification number. Namely, to input an identification
number, the user has to input the discrimination code "~k"
beforehand, so that the characters following the discrimination
code-"~k" can be recognized as an identification number.
when reception of the identification number could not be
recognized in step 511, the processing shifts to step S8, and
the call setting is restricted or refused as described above.
As described above, with Embodiment 3, an identification
number is inputted again in a case where an identification
number can not be discriminated from the data, so that correct
input can be completed before the call setting is executed even
if an identification number is incorrectly inputted or an
identification number is failed to be inputted, which makes it
possible to prevent call setting from being re-set before its
- 23 -
CA 02214197 1997-08-28
start.
In Embodiment 2, the call setting is restricted or refused
in the base station when an identification number is not
present in call-setting information, however, like in
Embodiment 4 described below, the base station may request re-
entry of an identification number to the telephone set just in
case it is failed to be inputted or some other reason.
A base station and a telephone set according to Embodiment
4 are configured by the blocks shown in Fig. 4 and Fig. 5 like
those in Embodiment 2, so that the same reference numerals are
assigned to the units corresponding to those in Fig. 4 and Fig.
5, and description on the configuration and the functions is
omitted herein.
Next description is made for operations. In this description
on the operations, the same step numbers are assigned to each
of the processing corresponding to those in Embodiment 2, so
that description thereof is omitted herein, and description is
made herein only for different processing therefrom.
Fig. 8 is a flow chart for explanation of operations for
call setting according to Embodiment 4 of the present
invention. In Embodiment 4, like in Embodiment 2, the
operations from step S21 to step S28 are executed, however,
when existence of an identification number can not be
recognized in data in the base station, re-entry of an
identification number is requested to the telephone set of the
- 24 -
CA 02214197 1997-08-28
originating user.
Namely, when existence of an identification number ID
therein could not be recognized in data in step 523, the
processing shifts to step S29 and requests input of the
identification number to the telephone set of the originating
user before the operation is shifted to execution of the call
setting. The telephone set having received the request
therefrom uses methods, to notice it to the user, of displaying
the request indicating re-entry of the identification number by
the user on the display section 7 as a message thereto, of
outputting it through the speaker 9 as an aural guidance, or of
outputting it through the speaker 9 as a notice sound.
After this operation, when an identification number is
transmitted from the telephone set of the originating user, the
received characters are accepted as an identification number
(step S30). However, when the line is requested to be
disengaged or the like from the telephone set, other processing
in response to the request is executed by departing from the
flow chart shown in Fig. 8.
When reception of the identification number could be
recognized in step 531, the processing shifts to step 524, and
the identification numbers are verified against each other as
described above. After this operation and on, the same
processing as that in Embodiment 1 is executed. It should be
noted that the code "*" has to be provided in front of a numeric
- 25 -
CA 02214197 1997-08-28
array of the identification number to recognize the
identification number, and for this reason, to input an
identification number by the originating user, the user has to
input the discrimination code "*" beforehand, so that the
characters following the discrimination code "*" constitute an
identification number.
When reception of the identification number could not be
recognized in step 531, the processing shifts to step 528, and
the call setting is restricted or refused as described above.
As described above, with Embodiment 4, the telephone number
as well as the identification number inputted with one
operation in the side of the telephone set are discriminated
from each other with the discrimination code in the side of the
base station, so that, when call-setting information is to be
inputted in the side of the telephone set, an telephone number
as well as an identification number can continuously be
inputted if the discrimination code is inputted therebetween,
so that the side of the base station can process verification
of the identification number as well as call setting as a
single unit.
In Embodiment l, there is not described in detail on re-
setting of restriction of the functions needed after the
functional restriction has been unlocked for execution of call
setting, however, like in Embodiment 5 described below,
restriction of the functions may be programmed to automatically
- 26 -
CA 02214197 1997-08-28
be re-set after execution of the call setting.
A telephone set according to Embodiment 5 is configured by
the blocks shown in Fig. 1 like that in Embodiment 1, so that
the same reference numerals are assigned to the units
corresponding to those in Fig. 1, and description on the
configuration and the functions is omitted herein.
Next description is made for operations. In this description
on the operations, the same step numbers are assigned to each
of the processing corresponding to those in Embodiment 1, so
that description thereof is omitted herein, and description is
made herein only for different processing therefrom.
Fig. 9 is a flow chart for explanation of operations for
call setting according to Embodiment 5 of the present
invention. In Embodiment 5, like in Embodiment 1, the
operations from step Sl to step S8 are executed, however, the
telephone set has processing for re-setting the functional
restriction therefor after the call setting is executed.
After the functional restriction is unlocked in step 6, and
when the call setting starts to be executed in step 7, the
unlocked state thereof is maintained during the execution.
Then, when a call or a data communication is ended according to
the call setting (step S12), the processing shifts to step S13
to re-set the functional restriction. With this re-setting, the
functional restriction having been set before being unlocked in
step S6 is recovered.
- 27 -
CA 02214197 1997-08-28
As described above, with Embodiment 5, even if call
restriction is unlocked once for execution of call setting, the
call restriction is programmed to automatically be re-set after
its being unlocked, so that it will not be failed to set the call
restriction and inconvenience due to re-setting of the call
restriction can be eliminated, which makes it possible to
simplify the setting operations for security functions under
such a condition that the security functions have been assured
during the operations.
In Embodiment 2, there is not described in detail on re-
setting of restriction of the functions needed after the
functional restriction has been unlocked for execution of call
setting, however, like in Embodiment 6 described below,
restriction of the functions may be programmed to automatically
be re-set after execution of the call setting.
A base station 100 and a telephone set 200 according to
Embodiment 6 are configured by the blocks shown in Fig. 4 and
Fig. 5 like those in Embodiment 2, so that the same reference
numerals are assigned to the units corresponding to those in
Fig. 4 and Fig. 5, and description on the configuration and the
functions is omitted herein.
Next description is made for operations. In this description
on the operations, the same step numbers are assigned to each
of the processing corresponding to those in Embodiment 2, so
that description thereof is omitted herein, and description is
- 28 -
CA 02214197 1997-08-28
made herein only for different processing therefrom.
Fig. 10 is a flow chart for explanation of operations for
call setting according to Embodiment 6 of the present
invention. In Embodiment 6, like in Embodiment 2, the
operations from step S21 to step S28 are executed, however, the
telephone set has processing for re-setting the functional
restriction therefor after the call setting is executed.
After the functional restriction is unlocked in step 526,
and when the call setting starts to be executed in step 527,
the unlocked state thereof is maintained during the execution.
Then, when a call or a data communication is ended according to
the call setting (step S32), the processing shifts to step S33
to re-set the functional restriction_ With this re-setting, the
functional restriction having been set before being unlocked in
step S26 is recovered.
As described above, with Embodiment 6, even if call
restriction is unlocked once for execution of call setting, the
call restriction is programmed to automatically be re-set after
its being unlocked, so that setting the call restriction is not
a load on the side of the telephone set and inconvenience due
to re-setting of the call restriction can also be eliminated
therein, which makes it possible to simplify the setting
operations for security functions under such a condition that
the security functions have been assured during the operations
on the system.

Herein, combination of the invention according to Embodiment
3 and that according to Embodiment 5 is made as an invention
according to Embodiment 7, and re-entry of an identification
number may be requested to the user just in case it is failed
to be inputted or some other reason anc~ t-rA f,~nr.t; ~n~,
restriction may automatically be re-set after execution of the
call setting.
A telephone set according to Embodiment 7 is configured by
the blocks shown in Fig. 1 like that in Embodiment l, so that
the same reference numerals are assigned to the units
corresponding to those in Fig. 1, and description on the
configuration and the functions is omitted herein.
Next description is made for operations. In this description
on the operations, the same step numbers are assigned to each
of the processing corresponding to those in Embodiments 1, 3,
5, so that description thereof is omitted herein, and description
is made herein only for different processing therefrom.
Fig. 11 is a flow chart for explanation of operations for
call setting according to Embodiment 7 of the present
invention. In Embodiment 7, like in Embodiments l, 3, 5, the
operations from step S1 to step S13 are included.
Namely, when existence of an identification number ID could
not be recognized in data in step S3, the processing shifts to
step S9 and requests input of the identification number to the
user before the operation is shifted to execution of the call
- 30 -
CA 02214197 1997-08-28
setting. There are used methods, for this request, of
displaying the request indicating re-entry of the
identification number by the user on the display section 7 as
a message thereto, of outputting it through the speaker 9 as an
aural guidance, or of outputting it through the speaker 9 as a
notice sound.
After this operation, when the key operation by the user is
received, the received characters are accepted as an
identification number (step S10). When reception of the
identification number could be recognized in step 511, the
processing shifts to step S4, and the identification numbers are
verified against each other as described above.
After the call setting is executed in step 7, and when a
call or a data communication is ended (step S12), the
processing shifts to step S13 to re-set the functional
restriction. With this re-setting, the functional restriction
having been set before being unlocked in step S6 is recovered.
It should be noted that, when reception of the
identification number could not be recognized in step 511, the
processing shifts to step S8, and the call setting is restricted
or refused as described above.
As described above, with Embodiment 7, an identification
number is inputted again when an identification number can not
be discriminated from the data, so that correct input can be
completed before the call setting is executed even if an
- 31 -
CA 02214197 1997-08-28
identification number is incorrectly inputted or an
identification number is failed to be inputted, which makes it
possible to prevent call setting from being re-set before its
start.
Also, even if call restriction is unlocked once for
execution of call setting, the call restriction is programmed
to automatically be re-set after its being unlocked, so that the
call restriction is not failed to be set in the telephone set
and inconvenience due to re-setting of the call restriction can
also be eliminated therein, which makes it possible to simplify
the setting operations for security functions under such a
condition that the security functions have been assured during
the operations.
Herein, combination of the invention according to Embodiment
4 and that according to Embodiment 6 is made as an invention
according to Embodiment 8, and re-input of an identification
number may be requested to the telephone set just in case it
is failed to be inputted or some other reason and the
functional restriction may automatically be re-set after
execution of the call setting.
A base station and a telephone set according to Embodiment
8 are configured by the blocks shown in Fig. 4 and Fig. 5 like
those in Embodiment 2, so that the same reference numerals are
assigned to the units corresponding to those in Fig. 4 and Fig.
5, and description on the configuration and the functions is
- 32 -
CA 02214197 1997-08-28
omitted herein.
Next description is made for operations. In this description
on the operations, the same step numbers are assigned to each
of the processing corresponding to those in Embodiment 2, 4, 6,
so that description thereof is omitted herein, and description
is made herein only for different processing therefrom.
Fig. 12 is a flow chart for explanation of operations for
call setting according to Embodiment 8 of the present
invention. In Embodiment 8, like in Embodiment 2, 4, 6, the
operations from step S21 to step S33 are included.
Namely, when existence of an identification number ID
therein could not be recognized in data in step 523, the
processing shifts to step S29 and requests transmission thereto
of the identification number to the telephone set of the
originating user before the operation is shifted to execution
of the call setting. After this operation, when an
identification number is received from the telephone set
thereof, the received characters are accepted as an
identification number (step S30). When reception of the
identification number could be recognized in step 531, the
processing shifts to step 524, and the identification numbers
are verified against each other as described above.
After the call setting is executed in step 527, and when a
call or a data communication is ended (step S32), the
processing shifts to step S33 to re-set the functional
- 33 -
CA 02214197 1997-08-28
restriction. With this re-setting, the functional restriction
having been set before its being unlocked in step S26 is
recovered.
It should be noted that, when reception of the
identification number could not be recognized in step 531, the
processing shifts to step S28, and the call setting is restricted
or refused as described above.
As described above, with Embodiment 8, the base station
requests to the telephone set to input an identification number
again when an identification number can not be discriminated
from the data, so that correct input can be completed before
the call setting is executed even if an identification number
is incorrectly inputted or an identification number is failed
to be inputted, which makes it possible to prevent call setting
from being re-set before its start on the system.
Also, even if call restriction is unlocked once for
execution of call setting, the call restriction is programmed
to automatically be re-set after its being unlocked, so that
setting of the call restriction is not a load on the side of the
telephone set 200 and inconvenience due to re-setting of the
call restriction can also be eliminated therein, which makes it
possible to simplify the setting operations for security
functions under such a condition that the security functions
have been assured during the operations on the system.
In the embodiments 1 to 8, the "~k" key 6a is used as
- 34 -
CA 02214197 1997-08-28
discrimination code, however, any key such as a key "~$" or the
like- may be used therefor so long as it is a key which can
discriminate between a telephone number TEZ and an identification
number ID, namely a key other than ten key.
Also, in the embodiments 1 to 8, the discrimination code is
set to one character of "*°' obtained by one operation, however,
it may comprises a plurality of characters, and in this case,
there occur a plurality of combinations thereof as
discrimination code. For this reason, call setting can be
executed only when correct discrimination code and a correct
identification number are inputted to a telephone set, which
makes it possible to improve security effects thereof.
As described above, with the present invention, when setting
a call, a user inputs call-setting information including a
telephone number and an identification number; the
identification number is determined from the call-setting
information and is collated to the previously registered
identification number; and specified call restriction is
unlocked only when the inputted identification number and the
previously registered one are identical. With this feature,
there is provided the effect that an input operation when
setting a call is to be executed only once and it is possible
to simplify the operation for call setting.
With another feature of the present invention, a telephone
number and an identification number inputted all at once are
- 35 -
CA 02214197 1997-08-28

code, and with this feature there is provided the effect
that, when inputting call-setting information, it is possible
to continuously input a telephone number and an identification
number by inputting a discrimination code therebetween.
With another feature of the present invention, when an
identification number is not determined, the user is asked to
input the identification number again, so that, even if input
miss for an identification number occurs or an identification
number is not inputted, the user can complete input of correct
information before call setting is executed, and with this
feature, there is provided the effect that the necessity for
retry of call setting can be eliminated.
with another feature of the present invention, even if call
restriction is once unlocked for execution of call setting,
the call restrictions are automatically set again, so that it
is possible to prevent a user from forgetting execution of an
operation for call restriction and also trouble for setting the
cal restriction again is saved, and with this feature there is
provided the effect that it is possible to simplify an
operation for setting the security function while maintaining
the security function.
With another feature of the present invention, when setting
a call, a user inputs call-setting information including a
telephone number and an identification number in the side of a
- 36 -
CA 02214197 1997-08-28
telephone set; the call-setting information is transmitted
to a base station; the base station receives the call-setting
information, determines an identification number from the call-
setting information to collate it to the previously registered
identification number, and unlocks call restriction and
executes call setting when the inputted identification number
and the previously registered identification number are
identical, so that an operation for inputting when setting a
call is to be executed only once in the side of a telephone
l0 set, and with this feature there is provided the effect that
it is possible to obtain a communication system in which the
call setting operation following security functions on the
system can be simplified_
With another feature of the present invention, a telephone
number and an identification number inputted all at once in the
side of a telephone set are discriminated by checking a
discrimination code in the side of a base station, so that, when
inputting call-setting information in the side of a telephone
set, it becomes possible to continuously input an telephone
number and an identification number on the condition that also
a discrimination code is inputted, and with this feature there
is provided the effect that verification of an identification
number and call setting can be executed in batch in the side of
the base station.
With another feature of the present invention, when an
- 37 -
CA 02214197 1997-08-28
identification number inputted in the side of a telephone set
can not be identified, a base station requests a user to input
the identification number again, so that, even if an user makes
a mistake in or forgets inputting an identification number, the
user can complete a correct operation for inputting call-
setting information, and with this feature, there is provided
the effect that it is possible to obtain a communication system
in which the necessity for executing an operation for call
setting again on the system is eliminated.
With another feature of the present invention, even if call
restriction is unlocked for execution of call setting, the call
restriction is automatically set, so that a work load for a user
to set call setting in a telephone set is eliminated and also
